Abstract
Objective To investigate the outcome of wavefront-guided laser in situ keratomileusis( LASIK ) for myopia. Methods Forty eyes in 21 patients with myopia undergoing wavefront-guided LASIK were collected as wavefront group, and 31 eyes in 16 patients with myopia receiving LASIK were chosen as control group. All patients were followed-up for one year. Visual acuity, refraction and high-order aberrations( HOAs )were examined before and after operation. The outcomes between two groups were compared. Results After followed-up,uncorrected visual acuity( UCVA )of all eyes were higher than 0.8. UCVA achieved 1.0 or better in 97.5% of eyes in wavefront group and 96.8% in control group. UCVA achieved 1.5 or better in 35.0% of eyes in wavefront group and 16.1% in control group. A total of 37.5% of eyes exceeded the preoperative best corrected visual acuity( BCVA )in wavefront group and only 19.4%in control group, but the difference was not significant( P> 0.05 ). The eyes with postoperative refractions within ± 0.5 D and within ± 1. 0D accounted for 75% and 95% in wavefront group,and 77.4% and 93.5% in control group,respectively,but there was no significant difference in postoperative refractions between two groups( P > 0.05 ). One year after the operation, total HOA, coma and spherical values increased in two groups, but the values were lower in wavefront group than in control group( P <0.05 ). Conclusion Compared with conventional LASIK,wavefront-guided LASIK has no advantage in improving uncorrected visual acuity, but wavefront-guided LASIK is more efficient to reduce the higher order aberration after operation.关键词
